I don’t know why people insist on planting land mines. There is a tool for managing workgroup arrays called foo. Among its many operations it had: $ foo reset array $ foo reset array controller a|b The first one resets to factory defaults. The second reboots one of the redundant controllers, a or b. We had to reconfigure and restore from tape several times. In zfs the command to create a dataset is “zfs create toplevelname/datasetname”. The command to create a snapshot is “zfs snapshot datasetname@snapshotname”. The command to destroy either is “zfs destroy objectname”, and the objectname of a snapshot is always a valid dataset name plus an at sign plus the snapshot name. Deleting a dataset is not a reversible operation. :/
